The wavefunction for a particle in a one-dimension box is a well-known problem, which has as a solution:
Ψ(x) = √(2/l) sin (nπx/l)
When the box has three dimensions, the general solution is simply the multiplication of the solutions for each dimension, therefore:
Ψ(x) = K · sin (n_x·π·x / l) · sin (n_y·π·y / l) · sin <span>(n_z·π·z / l)</span>
Answer:
![8\frac{ft}{sec}](https://tex.z-dn.net/?f=8%5Cfrac%7Bft%7D%7Bsec%7D)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or ![y=k/x](https://tex.z-dn.net/?f=y%3Dk%2Fx)
Let
x-----> the speed of the elevator
y----> the weight it carries
so
![y*x=k](https://tex.z-dn.net/?f=y%2Ax%3Dk)
<em>Find the constant k</em>
For x=10 ft/sec, y=400 lb
substitute
![k=10*400=4,000](https://tex.z-dn.net/?f=k%3D10%2A400%3D4%2C000)
The equation is
![y*x=4,000](https://tex.z-dn.net/?f=y%2Ax%3D4%2C000)
Find the speed for y=500 lb
substitute in the equation
![500*x=4,000](https://tex.z-dn.net/?f=500%2Ax%3D4%2C000)
![x=4,000/500=8\frac{ft}{sec}](https://tex.z-dn.net/?f=x%3D4%2C000%2F500%3D8%5Cfrac%7Bft%7D%7Bsec%7D)
